AMD FX-8120 Vs Core i5-2500K

– The FX-8120 is the bulldozer processor from AMD, while the Core i5-2500K is the Sandy Bridge processor form Intel.
– The FX-8120 is an eight core processor ( going by AMD’s terminology) while the i5-2500K is quad core.

– The FX-8120 has slight edge over the Intel’s i5-2500K. Its lead increases for highly multithreaded computing.

– The i5-2500. however, comes with HD Graphics 3000 integrated graphics. It does not has great performance but is good enough for encoding and decoding videos and seamless dual displays. You will still need a graphics card for high end gaming.

– FX-8120 is about $40 cheaper than the i5-2500K at the time of writing ( $189.99 Vs $229).

If you can make use of the integrated graphics of i5-2500K ( and you are not into gaming), it is an excellent solution. If you need a graphics card anyway, the bulldozer FX-8120 turns out better, as, it will give you better graphics performance when paired with an external graphics card.
